Vista - Help Needed PC is Crashed

Well here is the situation, i had just finished browing forums and chatting with friends online, so i decided to go to sleep, after waking up i tried to start my pc only to see Vista start loading up followed by a black screen, after asking what happened i was told that my 14 year old brother was messing around with my pc and just going to sites that i told him not to, apparently he may have snatched a virus from one of these sites, ive tried a few of the guides on here and the only thing i see left is to wipe the hard drive clean and reinstall everything but even my recovery disc wont wont work, when i go to repair your computer the list thats supposed to show up doesnt even show, it says windows is loading files, then it goes to the loading screen and goes black again then i get a message stating that a hardware or software change may be causing the problem, im at my end here and im about to beat my brothers ass, someone please help me, how can i reformat my pc, its a gateway GT5404

Have a very serious problem going on and was wondering if someone can please answer the thread instead of just viewing it? i would greatly appreciate it.

Call your psychologist....

What is the problem ?

lol im serious please help man, my brother messed my pc up and i need to reformat. but whatever he did i cant even get my recovery disc to work everything gets bypassed.

1. What does "messed up" mean exactly ? Hardware issue ? Vista Issue?

2. What is the PC doing that causes you to believe that you need to reformat your hardrive ?

3. Do you have an anti virus protection on the PC ?

4. Can you boot up in Safe Mode ?

5. Where did your brother go that has caused these problems ?

Provide more descriptive analysis as to what your pc is doing...?

You either have a bad disk.

The wrong disk.

A peice of your hardware has gone bad, probably your harddrive.

Or installing windows is more then you can handle.

Take the system in for repair to someone who does know what they are doing.

check the video driver settings first....

Well it starts to boot up and then the screen goes black and stays there, wont go to the desktop at all, no matter what i try everything just gets bypassed, recovery disc wont even work it says windows is loading files, then the same vista loading screen comes again, then the black screen after.

how do i do that?
